what is the dynamic pressure in psi at say 37.000 flying .79?
Ans = 1.3769 psi.

Atmospheric pressure at 37,000 ft = 3.1518 psi
so the dynamic pressure at 0.79M is less than half of the static pressure.

If the front window blows out at 37,000 alt, the dynamic pressure + static pressure = 4.5 psi which is equivalent to an ALT of about 29,000 feet.
